'VENTILA'IOR non FARM BUILDINGS.

Application filed m 2,

invention relates to ventilators of the kind used for controlling the supply of fresh air for farm buildings.

More particularly, it is my object to provide such a ventilator of the-type having openings covered by fabric, such for example as muslin, whereby a prop'er'volume of fresh air may be supplied to theebuilding with a minimum of variationin draft due to wind.

Another object is to provide such a ventilator having movable parts for controlling the flow of air.

- tor embodying my invention installedon a With these and'other objects in view, my invention consists in the construction, jar- F rangement and combination of the various parts of my ventilator forfarm buildings whereby the objects contemplated" are at-. tained, as hereinafter more fully set forth,

pointed out in my claims, and illustratedin the accompanying drawings,'in. which: if I Figure 1 is (i-perspective viewof a ventilabarn roof. I g V Figure 2 1s a vertical, central,"sect1onal View through the ventilator.

Figure I 8 is a horizontal, sectional view taken on the line 3'3 of Figure 2; and

Figure 4 is a. sectional VleW taken onthe line4- 4'of Figure 2. v 1 1 Inthe drawings herewith, I have used the reference numeral 10 to indicate generallyth'e' roof of a barn or other farm buildin My improved ventilator has asuita le base 12, shaped to fit the roof and provided with the ordinary flashing 14.

Extending upwardly fromf the base l2is the ventilator body, which is rectangular in shape, and has the four side walls indicated generally at A. V l 7 Each side wall has the greater part of its central portion cut out to form'preferably a square opening 16 of substantially the same v area as the opening at the bottom of the ventilator body A.

The opening in the barn roof indicatedat 18 is of substantially the same area as that of each of the holes 16, and should be approxi mately one square foot for each six hundred cubic feet of air space in the building.

The walls A extend upwardly substantially above the openings 16 as clearlyillustrated in Figure 2.

On the inside of one wall A are supporting clips or the like 20, located above the openlinks 52 is a spacer-washer 62.

ing-s 16, and the opposite wall has near its side edges the spring clips .22.

I provide a rectangular frame 24 adapted to have one edge rest on the spring clips 22.

The walls Al have an inwardly extending flange 26 ust above theframe 24. The frame 24 isv covered with fabric 28, such as muslin as illustrated in Figure 2.

A fabric cover 30 is extended around the body A ofthe ventilator and is ofsutlicient size to fully cover the openings 16. It may be fastened in place in any suitable way. I 1

- The walls A have their upper corners inclined as at 32. Seated on the inclined edges of the walls A is the'roof or top B of the ventilator, which-may have any shape fanciful or otherwise suitable for the purpose. As

shown, the roof is in the fformof four,

wardly from the wall A and opening 36is-a triangular baflle plate 40, extending downw'ardly below the upper edge of theadj acent roof A. This leaves a narrow space 42 betweeneach baffle plate 40 and the upper part of the adjacent wall A and the screen 38 thereabove. y

In the lower part of the body A of the ventila'tor is. a closu'redevice, which may be of any suitable kind. As shown, it consists oftwo wings 44 and 46 pivoted at theirends, preferably in the opposite walls A, by means of shafts48, securedto the wings 44 and. journaled in the opposite walls A.

'Secured to each of "the wings 44 and 46 nearone end thereof adjacent to their meeting edges are cars 50. Pivoted to each ear 50 is a link 52, which extends upwardly. The" upper ends of the links 52 are pivoted as at 54 to a'controlling rod 60, which hangs downwardly as shown in Figure 2. j

Between the controlling rod 60 and the The rod 60 slides through mounted on the inner side of one of the walls A at its lowerv part.

Inside the base 12 is a cross member 66,

which serves as abase and also as a support a guide clip 64 I for another guide clip 68. The rod 60fslides between the uide clip 68 and the base 66. The guide clip 68 is slidably mounted on small posts 70 supported by the. guide 66. On the posts 70 are mounted coil springs 72 for yieldingly holding the guide clip 68 against the rod 60 for thus frictionally holding the rod60 and the wings 44: and 46 in any adjusted position.

In the practical use of my improved venti la-tor, it is installed for instance in the manner shown and explained herein. r

The amount of ventilation desired may be controlled very largely by regulating the positions of the wings Mr and 46.

I find that by using the fabric covering and the fabric 528, adequate ventilation is secured withoutthose variations and sudden drafts, which are likely to occur, when there is a direct unimpeded flow ofair through the ventilator. l V v It is hard to control the ordinary ventilator without the requirement of too much and too constant attention, when there is a wind blowing.

. A ventilator of this kind affords much more nearly a; uniform supply of fresh air regardless of variations in wind velocity.

In the summer When-a direct air fl ow unimpeded by the fabric is desired, "he wings 4,4 and 46 may be opened, and by pressing the clips22 closely against the adjacent wall A, the frame Qmay be removed for allowing free flow through the pa-ssages l2,.the ope-nings 36 and then down through theventilator body.

In windy or more particularly in 7 cold weather, the frame 24 may be replaced.

It will, of course, be understood that my ventilator may be made of any suitable mate rial andthat the shape and particularly the shape of the roof may be changedas may be desired. j

The ventilator is intended to be made in various sizes for different buildings.

It is my intention to cover by. the claims of the. patent to be issued upon my application any modifications of structure, shape or aropenings in the side walls;

having openings in its side walls and fabric covers therefor, a fabricpartition at the top of said body, and-arroof for said ventilator, said ventilator beingprovided with openings at the upper part of its side walls between said walls and the roof, said roof having baffle plates extending from its upper "portion on its under side downwardly .tothe tops of said first .2; A'ventilator comprising a hollow body having openingsin its side walls and, fabric covers therefor, a fabric partition'at the top of said body,-a roof f 2 said ventilatonsaid ventilator being provided-with openings at the upper part of its side walls between said walls and the roof, said roof having baflle plates extending from its upper portion on its under slde downwardly to the tops of said lirst openings. in the side walls, and an adjustable closure device in the lower part of the ventilator body.

3. A ventilator comprising 'a hollow body having openingsin its side walls-and fabric covers therefor, a fabric partition in said body abovesaid-openings and a roof for said ventilator, said side walls being provided with openings above :said partition underneath said rooffor allowing the entrance of air be fore passing through said partition.

4. A ventilator comprising a hollow body having openings in its side wallsand fabric covers therefor, a fabric partition in said body supported. above said openings on a removable frame and a roof for said ventilator, said sidewalls being provided with openings between saidufi-rst mentioned openings and the roof for receiving air before it passes through said partition.
